What are the standards for qualified stainless steel thermos cups?

First of all, the stainless steel vacuum flask must be confirmed to be qualified before leaving the factory. The most critical test to test whether the material is qualified is the salt spray test. It is judged whether the material meets the standard through the salt spray test?Will it rust after long-term use?

In the water cup industry for so long, it can be said that. No matter how good the workmanship of the water cup is and how long the heat preservation performance is, as long as the material is not suitable or is different from the material indicated on the instruction manual, it means that this water cup is an unqualified product. For example: use 201 stainless steel to pretend to be 304 stainless steel, mark the 316 stainless steel symbol on the bottom of the water cup, pretend that the inner tank is made of 316 stainless steel, but in fact it is only 316 stainless steel at the bottom and so on.

Secondly, the tightness of the water cup. In addition to professional testing tools for tightness, the factory will adopt a sampling inspection method. Keep the lid upside down for half an hour with the water cup filled with water, then pick it up to check for leaks. Then invert the water cup and shake it up and down for 200 times, and check again whether there is any water leakage in the water cup.

The editor saw that many brands in a well-known e-commerce platform have a phenomenon of water leakage from consumers' negative comments in the water cup sales comment area. Such a water cup must be a substandard product, no matter how high-quality the material is, and no matter how cost-effective it is.

Then, thermal insulation properties. The editor of the international standard for stainless steel vacuum cups has mentioned it in other articles, and I will briefly talk about it today. Pour hot water at 96°C into the water cup, seal the lid, and open it after 6-8 hours to measure the water temperature in the cup. If the temperature is not lower than 55℃, it is a qualified thermos cup, so interested friends may wish to test it with their own thermos.

If the water bottle sold is clearly marked on the instruction manual or the packaging box, the heat preservation time is clearly marked.For example, some water cups will keep warm for up to 12 hours. Then, in the process of use, it can be considered that this water cup is a substandard product when it is found that it has not reached the advertised time.

There is another item that is also very important for the qualification of stainless steel thermos.Friends, do you want to know? If you have any, please leave a message, and the editor will announce the answer as soon as possible.
